In datacenters, humidifiers ensure above all that electrostatic discharges and damage to sensitive hardware are prevented. In addition, evaporative coolers can be used in the exhaust air cooling system, thus significantly reducing operating costs for cooling the servers.

The cooling effect achieved in the exhaust air is carried over to the intake air. Conventional cooling machines and cooling batteries can therefore be designed to be significantly smaller and more cost-effective. In addition to this, the ongoing operating costs for building cooling are reduced.
